Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

You'll need to create a material and assign it in your mesh. The material should have a parameter to change the color value.

From C++, you'll grab the assigned material on your mesh, create a MaterialDynamicInstance (so you can modify its values dynamically) and change the color using SetParameterValue

alt text

 AStaticMeshActor* SM = ...;
 UMaterialInterface* BaseMaterial = SM->GetStaticMeshComponent()->GetMaterial(0);
 UMaterialInstanceDynamic* DynamicMaterial = UMaterialInstanceDynamic::Create(BaseMaterial, SM, "MyMaterial");
 DynamicMaterial->SetVectorParameterValue("MyColor", FLinearColor::Red);
